A new discovery suggests gravitational fields can enable matter to become quantum entangled — and that's even if the concept ...

Kellogg Stelle was a professor of physics at Imperial College London for decades until his death last month. In 1977, he developed a particle theory of gravity that’s renormalizable, but the theory’s ...

From Fundamental Concepts to Dynamical Mechanisms, by Wolfgang Bietenholz and Uwe-Jens Wiese, Cambridge University Press.

For experimental physicists, the latest measurement of the muon is the best of times. For theorists there's still work to do.

Quantum gravity and field theory represent a frontier where the principles of quantum mechanics are reconciled with Einstein’s description of gravity. Researchers are seeking a consistent framework ...

The study of Dirac-harmonic maps sits at the intersection of differential geometry and quantum field theory, uniting concepts from harmonic maps and spinor fields into a single elegant framework.

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

Several leading quantum gravity theories predict that there is a dependence of the speed of light on photon energy, which ...

Classical physics theories suggest that when two or more electromagnetic waves interfere destructively (i.e., with their electric fields canceling each other out), they cannot interact with matter. In ...

So darkly complex, so fabulously remote from the familiar things of human existence is science’s probing into the fundamental secretae of the universe—of light, electricity, gravity, matter—that the ...
